After I entered my mail and hit enter, it reloaded the exact same frontpage without any notification. Therefore I didn't immediately know whether it worked or not.
Thanks. I didn't spend much time on the design of the site yet (which was really hard for me) because I wanted to get it launched quickly, but there is some text that shows up under the submit button after you click on it - Almost finished. We need to confirm your email address. To complete the subscription process, please click the link in the email we just sent you..
I will work on making that easier to see by maybe jumping to another page or something. It is a double opt-in list meaning you will get an email that you will have to click on to confirm. Let me know if you don't and I can look into it more.
